A little humor is in order to set the tone before I mention similar
news. Back in 2000, my wife at the time learned that I was on my way
to file for divorce. My job was working me long days and I'd come
home and pass out tired, so it was hard finding time to go see a
lawyer. My wife jumped me by a few days when her mother told her
that she would win the divorce if she filed first. To make a long
story short, because we had/have kids and she filed first, she
demonstrated first that she was unwilling to make the marriage work
in the kid's best interest. ANYWAY... jibberish chin wag chew blab
blab 11 years down the road we are friends but I have custody of the kids.
This 230400 bps stuff just reminded me of that for some reason. I
spoke of CoCoNet 2.0 having 230400 bps bitbanger support a few days
ago to a friend but I wanted to keep it silent to the masses to
introduce the next time I was gang busted by the "other guys", sort
of a debate-stopper if you will. We've seen all the numbers talk on
the forums and although I'm not a posting member I did notice my name
mentioned quite a bit. It's just nice to know we are all very active
and trying to improve on our stuff even though all of the products
are apples and oranges and can't be compared in a fair way.
Of course, I, too, owe credit to Darren Atkinson for our talks about
230400 bps bitbanger speed 2 years ago and I tested some code back
then as well. I've been so terribly busy that several years have
gone by without it being added to CoCoNet. Now the very few days I
was focusing on it in hopes to surprise the masses :) it may very
well now appear that when I do present this in CoCoNet that I would
have been the guy who copied the idea from the DW team.
I wanted to say early on that this is not the case and that we both
owe full credit to Darren Atkinson for sharing the idea and/or code
with both of us.
An early Cheers to getting this to work flawlessly eventually.
